jongo

Mongo in Java can be used with several tools: the 10gen official driver an alternative async Java driver a mapper — a library built on top of a driver — Morphia , Jongo ... ( see complete list ) Is there some benchmarks comparing mappers to drivers performances and one versus each others? Unfortunately, there are no benchmarks that I am aware of. The driver home page is here (but I'm guessing that you probably know that) and the Java Language Center containing all information related to Java for MongoDB. There is quite a bit of work going on with the Java drivers at present afaik but no

I want to serialize ObjectId of my Product class to JSON. I got the following JSON: [{"name":"Play for Java: Covers Play 2","type":"Book","company":"Manning Publications","price":30.0,"imagePath":"public/images/play-for-java.png","rating":4.5,"category":"Computer","author":"Nicolas Leroux","publicationDate":1396224000000,"numPage":320,"_id":539da7a6370882f10d5c2777}] You can notice that the "_id" didn't be properly serialized, it should be "539da7a6370882f10d5c2777" (with double quotes) and not just 539da7a6370882f10d5c2777 . Therefore, I have tried to implement my own ObjectIdSerializer as

In mongodb, I can do this by the following query: find( { _id : { $in : [ ObjectId('5275c6721a88939923c3ea54'), ObjectId('5275c6721a88939923c3ea55'), ObjectId('5275c6721a88939923c3ea56'), ObjectId('5275c6721a88939923c3ea57'), ObjectId('5275c6721a88939923c3ea58') ] } } ) But how can we do the same using Jongo code? I know we can find one document via: db.getCollection("mongoEg").findOne(Oid.withOid("5194d46bdda2de09c656b64b")).as(MongoTest.class); But how to get more than one documents in one query via Jongo? yves amsellem I see two options to achieve a find on multiple ids: // 1. find with an

Annotations in Kotlin can have different use-site targets as explained here: https://kotlinlang.org/docs/reference/annotations.html#annotation-use-site-targets My question is: When use-site is not explicitly defined, what is the default target when annotating property in a class like in the example below? class Test { @SomeAnnotation var someProperty: String? = null } Background I'm trying Jongo as MongoDB client in Kotlin and have problems annotating id field. Jongo does not map id property correctly when it's annotated like this: @MongoId @MongoObjectId var id: String? = null The annotations
